Bill,
The intake gasket was plastic with blue silicon rings surrounding the intake ports. Is this a vortec gasket? Being a pre vortec motor the intake manifold is a 12 bolt version. The motor also has center bolt valve covers vice the earlier motors that had the bolts on the edge of the valve cover.
With the coolant in the heat exchanger bubbling/burping and #6 spark plug very white, would this be caused by the faulty/incorrect intake gasket?
